OCZ Announces First AM2 Optimized Memory Kit that Makes Use of AMD's Memory Controller

The new PC2-5400 Titanium modules were designed exclusively for the AMD AM2 platform and are custom-tailored to the extended column address range of the AM2 memory controller. With a doubled page size, access penalties are reduced to improve system performance. Used on the AM2 platform, the architecture of these modules is particularly beneficial for large CAD model processing and memory intense graphics applications such as filters in Adobe Photoshop or video processing.

With 11 column address bit support by the AM2 memory controller, the number of addresses in each row or page can be as high as 2048 individual entries for a page size of 16kbit. Unlike modules based on standard 10-bit column address chips with an "8k" page size, the new Titanium AM2 Special modules take advantage of the AM2 controller?s feature set and provide a single rank solution with 2GB density using "16k" pages. This allows the controller to stay "in page" twice as long compared to standard memory architectures, thereby achieving higher performance.

"The biggest difference between synthetic memory benchmarks and real world applications is that only a fraction of memory requests falls into open memory pages," commented Dr. Michael Schuette, VP of Technology Development at OCZ Technology. "Even in page hit situations, larger size data transfers are hitting page boundaries, resulting page switching penalties and performance degradation. The new AM2 Special series uses twice the page size of standard memory, thereby greatly increasing the number of continuous page hits and delivering real world performance above and beyond any comparable memory solution at similar nominal rating."

The PC2-5400 AM2 Special modules will be initially available in 4GB (2x2048MB) dual channel kits and are optimized for 64-bit operating systems.
